Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is NOT a major enzyme of DNA replication?
A
RNA polymerase
B
DNA polymerase
C
Helicase
D
Topoisomerase
E
Primase
Explanation: 

Detailed explanation-1: -Lipase enzyme is not involved in the DNA replication process. DNA replication process requires DNA polymerase, DNA primase, DNA helicase, DNA ligase, and topoisomerase enzymes.

Detailed explanation-2: -Explanation: The enzyme DNAse do not participate in DNA replication, it is a DNA digestive enzyme that has no role in replication.

Detailed explanation-3: -DNA replication requires other enzymes in addition to DNA polymerase, including DNA primase, DNA helicase, DNA ligase, and topoisomerase.

Detailed explanation-4: -The central enzyme involved is DNA polymerase, which catalyzes the joining of deoxyribonucleoside 5′-triphosphates (dNTPs) to form the growing DNA chain. However, DNA replication is much more complex than a single enzymatic reaction.

Detailed explanation-5: -The four main enzymes involved in DNA replication are DNA helicase, RNA primase, DNA polymerase, and DNA ligase. There are other enzymes that are involved in DNA replication, but these four are the main players.
